| Description | During October 2004 and March 2005, groundwater samples from monitoring wells in downtown Montesano were collected for benzene, toluene, ethylbenzene, and xylene (BTEX) and total petroleum hydrocarbons as gasoline (TPH-G). High concentrations of gasoline-range petroleum hydrocarbons were detected in wells from three areas identified as potential sources: Tony’s Short Stop/Grays Harbor Grange, Key Bank (Sterling)/Whitney’s Inc., and Brumfield-Twidwell. Benzene concentrations did not meet (exceeded) the Model Toxics Control Act Method A cleanup standard of 5 ug/L in 10 of the 32 wells, with concentrations ranging from 5.1 to 8500 ug/L. TPH-G concentrations exceeded the standard of 800 ug/L in nine wells, with concentrations ranging from 1100 to 81,000 ug/L. |
